testoprim-d PAIN HELP!!!

Hey whats up? I'm doig a test only cycle . the 1st 2 wks i used 3 amps of primotesten no problem. any way i was only able to get 6 amps of primo so i had to switch to testoprim-d. my plan was to do 1 amp every mon. wend. &fri. the first 3 shots only hurt a bit. then tues. after my mon. shot i noticed it hurt pretty bad . anyways today is thur. and after my shot yesterday the pain is almost unbearable. this is my 3rd cycle and i've never felt pain even close to this bad. is it the prop? is it because im just rotating between sides of my ass. hell it hurts so much im seriously considering cutting my cycle short and throwing this shit away. but damn i love being on test . should i try boiling the shit . should i stat away from my ass for a while and rotate sites. any suggestions. if i throw this away i want be able to get any gear for at least 2 mos.:unsure:
